.x_t and .igs file imports

I just got a new copy of the SolidWorks 2007 base package and
I'mhaving some issues importing parasolid files. I've tried
toimport two different types of files and haven't been able to
openeither of them. When I look at them in Windows
Explorer,Windows doesn't actually recognize either of them as
SolidWorksfiles either (it hasn't assigned the appropriate app to
open them). Here's the errors I've been getting.

The only problem is, the guy sitting next to me is using
SW2005 andcan open that file with no problem.

The .x_t file is a bit more straightforward. Both of us
getan error that reads:

"Cannot open XXXXX.x_t"

I assumed that since it's a type of file that is in the file
typesdrop down field that SolidWorks could open it. That and
thevendor that sent us the file expected that it would work as
well. Am I missing something?

Zane,
why don't you post your parasolids and iges files and I'll see if I
can help with this.
My suspcion with the iges file is the version setting when opening
it. Check your import options. I'd doubt that 2007 would drop
support for a version, but it's possible.
The step file might have been a bad export. You might want to check
with your source on that.
As for windows not associating those files with Solidworks: this is
because those are nuetral file formats that don't belong to any one
vendor and can be read by man different programs. You can chage the
association if y ou want, by double-clicking the file and then
choosing the Solidworks program type when Window presents you with
a 'WTF?' dialog.
